SEALING-LIQUID-COLLECTING TANK FOR DISK-TYPE GASOMETERS.

Application filed July 7,

- resident of Mainz, Germany, have invented certain new and useful Improvements in Sealing-Liquid-Collecting Tanks for Disk- Type Gasometers, of which the following is a specification.

This invention relates to gasometers of the disk type, that is to say, in which the variable gas space is closed up byv a disk sliding gas-tight upon the inner wall of the gasometer.

In this type of gasometer the gas-tight seal between the wall of the gasometer and the sliding disk is formed by a liquid fillrn the narrow gap existing between the dis and the wall, and it has been found, thatthe most efficient way of sealing is to keep the liquid continuously running down the wall of the gasometer, the liquid being eventually collected at the bottom and returned into the distributor at'the top ofthe gasometer in order to be used again. V

The main object of the invention now 1s to provide efficient-and improved means for facilitating the collection and reemployment of the sealing liquid. 1

Further objects are the separation of undesirable matter from the sealing liquid while collecting, and the prevention of freez-' ing or congealing of the sealing liquid or the water separating therefrom.

According to the invention collecting tanks are provided in close proximity to the walls of the gasometer at the foot thereof and communicating with the same by means of a dip tube extending down to a relatively great depth below the liquid level in the collecting tank. The diameter of these d1p tubes is such as to allow of all undesirable matter specifically lighter than the sealing liquid, water for example, to accumulate at the top, whence it may be removed through a tap hole provided for the purpose.

In order to be able to remove the water in freezing weather, which ordinarily would be impossible owing to the ditliculty .of separating the ice crystals respectively, from the viscous gas tar generally employed as the sealing medium, heating devices are employed'which preferably consists of an ordinary tube arranged to extend across the 1923. Serial No. 650,022.

collecting tank and heated by a jet'of gas drawn directly from the gasometer. v

Modern gasometers'are often of very large dimensions; subsidences are likely to'occfur with the result that the liquid would collect at one side of the gasometer only, and in order to prevent this drawback, a turnable flap or gate is provided at the upper edges of the dip tubes, which may be operated from theoutside and whereby the overflow edges ofthe said tubes may be-raised or lowered as required.

Further objects and advantages of the invention will be apparent from the following description of the accompanying sheet of drawings, in which the invention is illustrated by way of example.

In these drawings,

Fig. 1 is a vertical section through one of the sealing liquid containers which, according to the invention, are spaced at convenient intervals around the gasometer.

Fig. 2 is a sectional plan view of the container or tank.

Figs. 3 and 4 are detail front and side elevations respectively illustrating the adjustable overflow for the liquid at. the top edges of the dip tubes.

According to these figures the liquid container is arranged in close proximity to the gasometer a at the foot thereof. As will be seen from the drawing the gasometer is built up of plate metal and the collecting tank b communicates with the same by means of dip tube 0 ofcomparatively large diameter which at one of its ends projects into the gasometer through the bottom thereof, whilst with its otherend it is arranged to extend down into the liquid collecting tank to almost the bottom of the same. The sealing liquid is distributed at the top of the gasometer and allowed to continuously run down the gasometer walls through the a between the said walls and the sliding already referred to and which is not shown in the drawing as it forms no part of the invention. The liquid accumulates at the bottom of the gasometer and eventually passes through the dip tubes 0 into the collecting tank 6.

As Willbe seen from the drawing, the

than in the tank itself, and the water or other undesirable matter separating therefrom will thus accumulate at the surface, being specifically lighter than the sealing liquid w ich generally consists of heav gas tar. From here the water or other undesirable matter may be drained ofi through a suitably positioned tap hole e. The latter, as shown in Fig. 1, is located at a place corresponding to the level of the liquid in the di tube 0. i

" Wit in the tank I) and outsidethe tube j c, a float f is arranged which, by means of a link gear f, is adapted to control an electric motor, or.other means, provided to drive a liquid circulating pump which is arranged in any well known manner to return the sealing li uid which has collected in the tank b to the istributor generally located at the top of the gasoineter. As the electric motor and circulating pump per se form no part of the invention, it has not been considered necessary to illustrate the same. The said pump is set in motion each time the sealing li uid has reached a certain level in the tan and is stopped as soon as sufficient liquid has been pumped up into the distributor at the upper art of the gasometer, whence it is allowe to run down the walls of the latter'as already described. It will thus be seen that the float f and the link gear f constitute means operated automatically by the variations in the liquid level in the collecting tank I) for controlling withdrawal of sealing liquid therefrom.

In order to enable such tapping of the water accumulating in the collecting 'tank to be effected also in freezing weather and to thus avoid disturbances in the circulation 40 of the sealing liquid, a heating tube 9 is arranged to exten across the collecting tank. A gas jet h burning'within this tube is fed dikrectly from the gasometerithrough the p1 e i 5 For reasons described in the opening paragraphs of this specification the overflow rom the gasorineter a into the di tube a is made to be adjustable in heigit. For this purpose a. se ment-shaped flap or gate k .is mounted fluid-tight in a notch 'i at the u per end of the dip tube c (Figs. 3 and 4; I This ate operates in the fashion of an ove ow weir and can be adjusted from the outside by means of a lever m as shown in Figs. 3 and 4. By means of this device the height of the overflow edge may be varied and the flow of the sealing liquid into the. coilecting tank regulated. The exact position of the gate is indicated at the 0 outside by the lever m functioning as a pointer and which may be arranged to move over. a graduated scale m. V

The number of liquid collectin tanks reqiliired for a gasometer largely depends on 66 t e size of the latter. It must be such as to insure a reliable collection and discharge of the sealing liquid on the one hand, and a satisfactory'supply of the liquid between the closing disk and the gasometer wall at the other hand. Z

In order to achieve the aforesaid object with certainty, each of the collecting tanks is preferably in connectionwith a separate pump for the circulation of the liquid. In this way the proper collect-ion and circulation of the liquid-may berelied upon and the installation yet be easily supervised.

What I claim is l. The combination of a disk type gasometer and a collecting tank for collecting the sealing liquid, a dip tube, the upper end of which tube communicates with the gasometer and the lower end of which tube projects below the surface of the liquid collected in said tank, the wall of said dip tube intermediate the ends thereof being provided with a tap hole for the withdrawal lected in said'tank, the wall of said dip,

tube being provided with a tap hole at a place corresponding to the liquid level in the tube for the dischargeof undesirable matter, a float mounted within said tank and means connected with said float and operated thereby to control the withdrawal of sealing liquid from said tank.
